Do the Celtics play tonight? Boston Celtics Schedule. Over 24,000 Celtics fans have downloaded this very small, fast app shows a simple Celts schedule with National TV (ESPN, NBATV, TNT) listings. So when you are walking around Boston and someone says: “do the Celts play tonight or Dude, when is the next Celts game?”. One tap of your Android phone tells you the answer!!! No thumbing through old months, this app knows today's date and quickly shows the next set of games from today's date to the end. I have been a HUGE Celtics fan since 1960. This app has no official affiliation with the Boston Celtics of the NBA.
